WE KNOW A “LITTLE” ABOUT VDI !

1. BYOD = (IOS + ANDROID + WINDOWS) + (SMARTPHONES + TABLETS + PCS)

§  Windows PCs are less than 20% of end points

§  Should you invest in fundamentally new infrastructure to run Windows?

§  Or should you look at other solutions for BYOD for iOS, Android, MacOS, and Windows?

2. POOR UX FOR ALL APPS

§  The goal of VDI is to centralize desktops in the data center - every user becomes a remote user.

§  Every application becomes a remote Windows App. This compromises the user experience.

§  Why should Web apps be treated like Windows Apps?

§  We can affect everything except latency - we can’t change the speed of light

§  Remote experience degrades significantly over 70 ms latency

§  Directly impacts degree to which you can centralize desktops

3. LAWS OF PHYSICS

4. MULTI-MEDIA

Video is one of the most challenging applications §  Best performance when

video leverages client side h/w decoder

§  Video delivery needs to bypass remoting technology in order to be of high quality

§  Directly contradicts goals of centralization and small client footprint

§  Real-time collaboration applications, e.g. VoIP and video conferencing, are highly sensitive to latency

§  Collaboration applications need to bypass remoting and run directly on client

§  Directly contradicts goals of centralization and small client footprint

5. COLLABORATION

6. STORAGE COST

§  Windows OS was designed for local storage

§  Desktop I/O is random, mostly write and unpredictable

§  Needs 100s of IOPS per desktop

§  Only SSDs can match the performance requirements of a VDI deployment

§  SSDs are expensive

7. LAYERING §  Persistent desktops require

lots of storage §  Non-persistent desktops often

don’t meet end user requirements

§  Layering technology from vendors like Unidesk or CloudVolumes can solve the problem

§  Layering is new technology and is unproven at scale

8. ANTI-VIRUS

§  Anti-virus software is very disk i/o intensive

§  Running anti-virus software in real time requires expensive SSD storage

§  Anti-virus software may conflict with layering technologies

9. BOOT STORMS

§  With physical machines, each desktop boots independently

§  When a VDI server or a data center goes down even momentarily, all desktops boot up at once

§  Storage systems cannot easily handle boot storms, unless you use SSD

§  SSD increases cost of deployment

§  You need to buy a high-end thin client if you need to handle multi-media or real-time collaboration

§  The cost of the thin client can often be equal to the cost of a low end PC

10. THIN CLIENT COST

TOP 10 REASONS WHY NOT TO CHOOSE VDI TO SOLVE BYOD

1.  BYOD = (iOS + Android + Windows) + (Smartphones + Tablets +PCs)

2.  Remote Windows Experience for all Applications

3.  Laws of Physics for latency cannot be changed

4.  Challenges with multi-media

5.  Challenges with collaboration tools like Lync

6.  Expensive Storage Required, including SSD

7.  Immature layering technology to reduce costs of storage

8.  Inability to run standard anti-virus software

9.  Boot storm issues

10.  Cost of end points – thin clients
